The specific embodiment
Below in conjunction with accompanying drawing utility model is further described, but is not limited to embodiment.
Embodiment 1
As shown in Figure 1 and Figure 2, the utility model comprise small displacement engine 3, the electrical generator 2 that connects by connecting device 8 and small displacement engine 3, with the engine controller 4 of electrical generator 2 by being electrically connected, with the apparatus for storing electrical energy 5 of engine controller 4 by being electrically connected, with the main electric machine controller 6 of apparatus for storing electrical energy 5 by being electrically connected, with main electric machine controller 6 by the drive motor 1 that is electrically connected and the drive axle 7 that links to each other by transmission shaft with drive motor 1.The integral body that connecting device 8 is made of in proper order fix shaft 8a, male splined shaft 8b and the inner spline housing 8d of concentric as shown in Figure 3; Surface working at male splined shaft 8b has male splines 8c; Inner spline housing 8d is the uncovered tube-in-tube structure of inner closed outer end, is processed with female splines 8e at sleeve lining, offers the pin-and-hole 8f of perforation on the sleeve of inner spline housing.Described small displacement engine 3 is not more than the driving engine of 2.0L for discharge capacity.Fill interface outside on apparatus for storing electrical energy 5, also being provided with.Solid line connection among Fig. 1 is expressed as mechanical connection, and the dotted line connection is expressed as and is electrically connected.
As shown in Figure 1 and Figure 2, large-scale hybrid power passenger car is with after the power system energized of small displacement engine, electrical generator 2 at first starts, after electrical generator 2 starts, electrical generator 2 drives small displacement engine 3 as " electrical motor " outputting power and starts, and behind small displacement engine 3 normal the startups, electrical generator 2 is outputting power no longer, electrical generator 2 changes into by small displacement engine 3 drive work, and electrical generator 2 enters power generation mode work.Electrical generator 2 is converted to electric energy with the mechanical energy that small displacement engine 3 produces, electric energy is delivered to apparatus for storing electrical energy 5 after by engine controller 4, electric energy is delivered to drive motor 1 again behind main electric machine controller 6, drive motor 1 will transmit the electric energy that comes and be converted to mechanical energy, be delivered to drive axle 7, drive axle 7 transmits wheel by mechanical connection with mechanical energy, the powered vehicle operation.
In the vehicle operating process, when electric energy closed-center system 5 electric weight (hereinafter to be referred as SOC) are lower than setting value or load when big, small displacement engine 3 drives electrical generators 2 work, electrical generator 2 generatings, when less the and SOC of load is higher than its default higher limit, driving engine 3 idling.In the vehicle operating process, mobile generator adopts " dynamic mode conversion " strategy, during by small displacement engine 3 work the bearing power of drive motor 1 is followed the tracks of charging: when the bearing power of drive motor 1 during less than 3 power that can export of small displacement engine, apparatus for storing electrical energy 5 storage excess energies; When the bearing power of drive motor 1 during greater than 3 power that can export of small displacement engine, apparatus for storing electrical energy 5 discharges electric energy, discharges electric energy and is used for replenishing the mobile generator energy output be made up of small displacement engine 3, electrical generator 2 and engine controller 4 and the difference between 1 energy requirement of drive motor; When the bearing power of drive motor 1 equals 3 power that can export of small displacement engine, apparatus for storing electrical energy 5 neither stored energy does not release energy again, the electrical energy transfer that is produced by mobile generator is to drive motor 1, drive motor 1 converts electrical energy into mechanical energy and is delivered to drive axle 7, the direct drive vehicle operating.
When adopting connecting device 8 to connect small displacement engines 3, fix shaft 8a is inserted in the knock hole of termination of driving engine,, prevent from effectively to protect driving engine because the transmission system overload causes engine off to guarantee the driving engine smooth running with electrical generator 2.When driving engine and electrical generator amplitude are inconsistent, also have regulating action, can resist impact effectively.Male splines 8c is connected with the clutch engagement of driving engine, and the other end cooperates connection by female splines 8e with male splines on the generator shaft, from the pin-and-hole 8f holding screw of packing into, to prevent generator shaft generation axial runout.This connecting device can be changed into the connecting mode of driving engine and electrical generator, connecting device one end connects with the power-transfer clutch of driving engine by male splines, the other end cooperates connection by female splines with male splines on the generator shaft, can guarantee that engine flywheel is coaxial with the electrical generator input shaft, and guarantee higher right alignment requirement, effectively solve the relatively poor problem of right alignment of traditional series hybrid electric vehicle driving engine and electrical generator coupling spindle.Adopt the power-transfer clutch connecting mode, also can increase certain adjusting flexibility, effectively solve shock resistance and driving engine and the inconsistent problem of electrical generator amplitude under different operating modes.
